TECHNICAL FIELD

Generally, the present disclosure relates to computer security. More particularly, the present disclosure relates to technologies for enhancing computer security.

BACKGROUND

In the present disclosure, where a document, an act and/or an item of knowledge is referred to and/or discussed, then such reference and/or discussion is not an admission that the document, the act and/or the item of knowledge and/or any combination thereof was at the priority date, publicly available, known to the public, part of common general knowledge and/or otherwise constitutes prior art under the applicable statutory provisions; and/or is known to be relevant to an attempt to solve any problem with which the present disclosure may be concerned with. Further, nothing is disclaimed.

Over the past few decades, the amount of data traveling between different entities/users has been growing exponentially. People/companies now rely on the internet to handle much of the business they conduct. This requires data to be sent between a source and a destination. For example, many companies have employees at many different offices at different geographical locations. Nonetheless, these offices need to be able to communicate effectively as if under the same roof. Accordingly, companies spend vast amounts of money attempting to ensure data communications across an external network, e.g., the Internet, remain secure. In other words, companies (and individuals) are constantly battling hackers who attempt to intercept these data communications.

To combat hackers, conventional data communication systems have relied on various methods for user authentication and/or access control, including encryption algorithms to encrypt data locally at a computer/server prior to that data being transmitted over an external network. Unfortunately, because many of these conventional systems are directly connected to an external network, hackers can simply use a “backdoors” of the local computes/serves to obtain data that is sought to be secured either before it is encrypted or after it is decrypted. Accordingly, there is a desire for more effective technologies for user authentication and/or access control are desired.

FIG. 1 shows a flowchart of an example embodiment of a method for enhancing computer security according to the present disclosure.

A process 100 includes blocks 102-118. Process 100 can be implemented via any combination of hardware logic, such as in one and/or more circuits on any hardware level, and/or software logic, such as in one and/or more software applications, which can be implemented below, on and/or above operating system level. Process 100 can be implemented in request-response computing. Process 100 can be a part of a larger process, irrespective of any relation to computer security. For example, various functions can be taking place before, during and/or after performance of any one and/or more blocks of process 100. Alternatively, process 100 can be performed on its own. Although blocks 102-118 can be performed in order as described herein, blocks 102-118 can be performed in other orders, with some blocks being performed before, during and/or after other blocks in any permutation thereof. Also, note that process 100 can be implemented with password entry, which can be based at least in part on alphanumeric input, symbolic input, biometric input, hardware input and/or others. However, process 100 can also be implemented without use of passwords.

Block 102 includes parsing a bit stream into a first plurality of equally sized strings. The bit stream includes a continuous sequence of bits, such as 101001001011110011, representing a stream of data over a medium. Such data can be of any type and/or for any purpose. The stream can be provided and/or received in a wired manner and/or in wireless manner. The stream can be communicated over a communication path via a communications protocol, such as a transmission control protocol (TCP), a user datagram protocol (UDP), and/or other network communication protocols of any communication range, and/or in computer memory and/or computer storage, such as a circuit, a non-volatile memory device, and so forth. The stream can be of any bit amount. The bit stream can contain information identifying a bit stream source and a bit stream destination. The bit stream can be a byte stream as well. The parsing into the first strings includes segmenting the bit stream into the first strings of any digit size, such as two, five, ten or any other number. For example, when the bit stream includes 101001001011110011, then such stream can be parsed into six digit strings, such as 101001, 001011, 110011 and so forth. The parsing into the first strings can occur on the entire bit stream and/or portions and/or sub-portions of the bit stream, irrespective of their size and/or relationship to each other. The parsing can be performed with and/or without interfering with the integrity of the bit stream. The parsing can be performed via at least one oscillator/clock. Alternatively, the sequence can be based on a different symbolic and/or numeral system, such as hexadecimal.

Block 104 includes parsing the bit stream into a second plurality of equally sized strings. The parsing into the second strings includes segmenting the bit stream into the second strings of any digit size, such as two, five, ten or any other number. For example, when the bit stream includes 101001001011110011, then such stream can be parsed into nine digit strings, such as 101001001, 011110011 and so forth. The parsing into the second strings can occur on the entire bit stream and/or portions and/or subportions of the bit stream, irrespective of their size and/or relationship to each other. The first strings have different size from the second strings. Although the first strings and the second strings are formed from parsing an identical portion of the bit stream, in other alternative embodiments, the first strings and the second strings can be formed from parsing different portions of the bit stream. The first strings can have different bit value from the second strings. The first strings can have identical bit value as the second strings. The first strings and the second strings can be equally sized and/or unequally sized. Block 102 and block 104 can be performed contemporaneously, concurrently and/or at different times by at least one entity. Block 104 can be performed before or after block 102. The parsing can be performed with and/or without interfering with the integrity of the bit stream. The parsing can be performed via at least one oscillator/clock.

Block 106 includes directing input of the first strings into a switch. The directing can include inputting at least one of the first strings into the switch. Alternatively, the directing can include sending at least one of the first strings into the switch. Also alternatively, the directing can include receiving at least one of the first strings via the switch. Also alternatively, the directing can include transmitting at least one of the first strings into the switch. The directing can be switch input demand based. The directing can be wired and/or wireless. The directing can be direct and/or indirect. The directing can be encrypted and/or unencrypted.

Block 108 includes directing input of the second strings into the switch. The directing can include inputting at least one of the second strings into the switch. Alternatively, the directing can include sending at least one of the second strings into the switch. Also alternatively, the directing can include receiving at least one of the second strings via the switch. Also alternatively, the directing can include transmitting at least one of the second strings into the switch. The directing can be switch input demand based, irrespective of any relation to any performance of block 106. Block 106 and block 108 can be performed contemporaneously, concurrently and/or at different times by at least one entity. Block 106 can be performed before or after block 108. The directing can be wired and/or wireless. The directing can be direct and/or indirect. The directing can be encrypted and/or unencrypted.

Block 110 includes periodically switching the switch between a first mode and a second mode. The switch can be hardware based, such as a circuit, and/or software based. The switch can be an A/B switch. Alternatively, the switch can be an A/B/n switch with n corresponding to a number of modes between which the switch can switch, which can be any, such as five, seven, nine, twenty and so forth. Periodically can be based on any time period, such as a milliseconds, seconds, minutes, hours and so forth. Such periodic switching is automatic. Such period can correspond to mode duration of the switch. The switching is based on a clock, an oscillator, a processor, and hardware and/or software logic. For example, such switching is every 30 seconds based on a clock. Therefore, for every 30 seconds, an A/B switch iteratively switches from the first mode to the second mode and from second mode to the first mode. Similarly, for every 30 seconds, an A/B/n switch iteratively switches from the first mode to the second mode, from the second mode to the n mode, and from the n mode to the first mode. Block 110 can be performed before, concurrently and/or at different times from any and/or all of blocks 102-108.

Block 112 includes outputting via the switch one of the first strings in the first mode. For example, when one of the first strings is 101001, then during the first mode, the switch outputs 101001. More than one string can be output in the first mode.

Block 114 includes authenticating/controlling access based on output of the first string. Therefore, when the switch outputs 101001, then the authenticating/controlling access is based on correct input of password 101001, whether in a binary form and/or another form, such as alphanumeric, symbolic, biometric and so forth. Block 112 and block 114 can be performed contemporaneously, concurrently and/or at different times by at least one entity. Block 112 can be performed before or after block 114.

Block 116 includes outputting via the switch one of the second strings in the second mode. For example, when one of the second strings is 101001001, then during the second mode, the switch outputs 101001001. More than one string can be output in the second mode.

Block 118 includes authenticating/controlling access based on output of the second string. Therefore, when the switch outputs 101001001, then the authenticating/controlling access is based on correct input of password 101001001, whether in a binary form and/or another form, such as alphanumeric, symbolic, biometric and so forth. Block 116 and block 118 can be performed contemporaneously, concurrently and/or at different times by at least one entity. Block 116 can be performed before or after block 118. Any and/or all blocks 112 and/or 114 can be performed after any and/or all blocks 116 and/or 118.

Using examples herein, when the switch switches back from the second mode to the first mode, then the switch outputs the next one of the parsed first strings. Therefore, in the next iteration of the switch in the first mode, the switch outputs 001011. Similarly, when the switch again switches to the second mode, then the switch outputs the next one of the parsed second string. Therefore, in the next iteration of the switch in the second mode, the switch outputs 011110011. Since such outputs function as passwords, authentication/access control is based on switching passwords, which when implemented, for example in a computer system, enhance security of the computer system. Resultantly, a computer outputting such code can be authenticated and/or granted access since such structure could not be figured out and/or reproduced without knowledge of original technological specifications, which can be preprogrammed in advance, such as via provision of a character sequence and subsequence generation methods. Such authentication/access control can facilitate in new computer language creation due to variation of what a byte is.

Note that the bit stream can be parsed into more than two pluralities of equally sized strings. For example, the bit stream can be split into any number of equally sized strings, such as three, nine, ten, twenty and so forth. The switch can switch between more than two modes. For example, the switch can switch between a plurality of modes, such as three, nine, ten, twenty and so forth. Accordingly, the switch can output based on the pluralities of equally sized strings in the plurality of modes. Such switch output can be used to authenticate/control access based on the pluralities of strings. Also, note that the switch can be local, such as a part of the computer or in a same locale as the computer, or the switch can be remote, such as network-accessible via the computer. Note that the switch can also be shared between the computers.

FIG. 2 shows a flow sheet of an example embodiment of a method for enhancing computer security according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.

A bit stream 202 is shown. Stream 202 contains a plurality of bits. Stream 202 is parsed into a first plurality of equally sized strings 204 and a second plurality of equally sized strings 206. The parsing can be performed via at least one oscillator/clock, such as one oscillator/clock operating according to one frequency and parsing into strings 204 and another oscillator/clock operating according to another frequency and parsing into strings 206. Strings 204 are parsed based on six digit segmentation and strings 206 are parsed based on nine digit segmentation. Therefore, strings 204 and strings 206 are different in bit size and have different string values. However, such segmentation can be based on any digit size and/or can share at least one value. The parsing into strings 204 and 206 can be performed contemporaneously, concurrently and/or at different times by at least one entity. Note that bit stream 202 can be the entire bit stream or a portion of some bit stream.

Each of the strings 204 is uniquely assigned to a plurality of first time periods. Such assignment can be performed on a one-to-one basis, one-to-many basis, many-to-one basis and/or many-to-many basis. For example, each of the strings 204 uniquely one-to-one corresponds to each of the first time periods, such as 1 sec per string. Similarly, each of the strings 206 is uniquely assigned to a plurality of second time periods. Such assignment can be performed on a one-to-one basis, one-to-many basis, many-to-one basis and/or many-to-many basis. For example, each of the strings 206 uniquely one-to-one corresponds to each of the second time periods, such as ½ second per string. Note that the first time periods and the second time periods start from a same point of reference or time zero. Note that the strings 204 and the strings 206 are contained via at least two different computers.

Strings 204 and strings 206 are then directed for input into a switch 208. As shown, switch 208 is an A/B switch automatically flipping back and forth between a first mode A and a second mode B every 30 seconds. However, switch 208 can be modal according to any number of modes and switch 208 can iterate through such modes as described herein. Further, switch 208 can receive input from other inputs whether related and/or unrelated to technologies as described herein. Strings 204 and strings 206 can be directed in any manner, whether contemporaneously, concurrently and/or at different times by at least one entity. At least one of strings 204 and at least one of strings 206 is input into switch 208, whether contemporaneously, concurrently and/or at different times by at least one entity. Switch 208 can be flipped for any time period based on any time measurement, such as a nanosecond, a millisecond, a second, a minute, an hour and so forth. Switch 208 flips automatically, which can include manual initial activation. Switch 208 switches based on a clock, an oscillator, a processor, and hardware and/or software logic. As shown, switch 208 switches every 30 seconds based on a clock. Therefore, for every 30 seconds, an A/B switch iteratively switches from the first mode to the second mode and from second mode to the first mode. Note that input into the switch can be based on a first-in-first-out (FIFO) methodology.

A plurality of time periods 212 is based on combination of the first time periods and the second time periods as shown with reference with strings 204 and strings 206. Time periods 212 can be based on different time measurements, such as time associated with strings 204 is based on seconds and time associated with strings 206 is based on milliseconds. Such different time measurements can be of any type.

When switch 208 is in the first mode, which can be the A mode, then at 12:00:00 as shown in time periods 212, switch 208 outputs one of strings 204, which as shown is 101001. Based on such output, authentication/controlling access is performed. For example, during the first mode, a password 210 can be 101001 or its value, such as in a decimal or a hexadecimal system, whether in a binary form and/or another form, such as alphanumeric, symbolic, biometric and so forth.

At 12:00:30 as shown in time periods 212, switch 208 flips to the second mode, which can be the B mode. During the second mode, switch 208 outputs one of strings 206, which as shown is 101001001. Based on such output, authentication/controlling access is performed. For example, during the second mode, password 210 can be 101001001 or its value, such as in a decimal or a hexadecimal system, whether in a binary form and/or another form, such as alphanumeric, symbolic, biometric and so forth.

At 12:01:00 as shown in time periods 212, switch 208 flips back to the first mode, which can be the A mode. During the first mode, switch 208 outputs the next one of strings 206, which as shown is 001011. Based on such output, authentication/controlling access is performed. For example, during the first mode, password 210 can be 001011 or its value, such as in a decimal or a hexadecimal system, whether in a binary form and/or another form, such as alphanumeric, symbolic, biometric and so forth. Such switch 208 flipping can continue indefinitely or until some condition is met. Since password 210 is switching as time as indicated by time periods 212 goes on, security of a computer system can be enhanced.

Note that bit stream 202 can be parsed into more than two pluralities of equally sized strings. For example, bit stream 202 can be split into any number of equally sized strings, such as three, nine, ten, twenty and so forth. Switch 208 can switch between more than two modes. For example, switch 208 can switch between a plurality of modes, such as three, nine, ten, twenty and so forth. Accordingly, switch 208 can output based on the pluralities of equally sized strings in the plurality of modes. Such switch 208 output can be used to authenticate/control access via password 210 based on the pluralities of strings.

For example, stream 202 and a plurality of different stream segmentation algorithms are provided to a plurality of computers, such as via preprogramming. Each of the computers segments stream 202, based on the algorithms, to result in strings 204 and strings 206, which are different from each other in size and/or value based on the algorithms. Strings 204 and strings 206 are input into local switch 208 alternating between a plurality of modes. The computers communicate with each based on password 210, which changes based on the switch alternating. Password 210 is periodically changed, according to time periods 212, based on alternating input from strings 204 and strings 206. The input is alternated according to the switch alternating between the modes. For the computers, password 210 change is synchronous, such as based on alternating of switch 208, but can be asynchronous. Also, for the computers, note that at least one of generation of strings 204 and strings 206 is synchronous, such as based on a clock, but can be asynchronous. Further, for the computers, note that input into switch 208 is synchronous, such as based on a clock, but can be asynchronous.

FIG. 3 shows a diagram of an example embodiment of a network according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.

A network diagram 300 depicts a network 300 in communication with at least a desktop computer 304, a tablet computer 306, a mobile phone 308, a laptop computer 310, a mainframe 312, a server 314, a cloud computing network 316, a communication tower 318, a satellite 320, another network 322 and a networking device 324. Such communication can be direct and/or indirect, wired and/or wireless, encrypted and/or unencrypted. Network 302 and/or network 322 can include Internet. More than one instance of any elements shown in diagram 300 can be included. Any and/or all elements shown in diagram 300 can communicate with any and/or all elements shown in diagram 300 in any way, whether wired and/or wirelessly. Any and/or all of such communications can be performed in any manner using technology as described in reference to FIG. 1 and FIG. 2. For example, a bit stream is received and parsed according to a first frequency of a first oscillator in a first manner and parsed according to a second frequency of a second oscillator in a second manner different from the first. The outputs of the first oscillator and the second oscillator are combined and used as a switch switching between alternatively outputting strings for network devices to focus on. When such output is incorporated into network communications, if output between communicating network devices are not identical, then such network communications are not allowed due to a changing authentication/access control condition.

In some example embodiments, the disclosed technologies can facilitate variation of what a byte is. Resultantly, the oscillation/clocking signal varies the bit length of how to segment the bit stream by parsing the bit stream into a variety of bit lengths to reinterpret the bit stream with the lengths encoding differently than network devices that interpret the bit stream into 8-bits, 16-bits and/or 64-bit increments. The length of bit stream increment is based on oscillator/clock frequency. At least two oscillators/clocks are used with a first oscillator/clock to generate the parsing or bit division and a second oscillator/clock synchronous to the first clock that interprets the parsing correctly. Without knowing the frequency of the first clock, the receiver of the signal will not be able to interpret the signal correctly using the standard 8-bit parsing. Thus, when a pair of oscillators/clocks having different frequencies are combined and their oscillations combined, then such combination creates a new waveform pattern that appears random, but does eventually repeat. The clocks can be atomic clocks, crystal based clocks, mechanical clocks and so forth. In some example embodiments, such technology can be combined with an identification number to create more secure network device access, irrespective of network device.

FIG. 4 shows a flowchart of another example embodiment of a method for enhancing computer security according to the present disclosure. Some elements of this figure are described above. Thus, same reference characters identify same or like components described above and any repetitive detailed description thereof will hereinafter be omitted or simplified in order to avoid complication.

A process 400 includes blocks 402-416. Process 400 is for encoding and decoding logic using variable lookup tables and/or word length. Process 400 can be implemented via any combination of hardware logic, such as in one and/or more circuits on any hardware level, and/or software logic, such as in one and/or more software applications, which can be implemented below, on and/or above operating system level. Process 400 can be implemented in request-response computing. Process 400 can be a part of a larger process, irrespective of any relation to computer security. For example, various functions can be taking place before, during and/or after performance of any one and/or more blocks of process 400. Alternatively, process 400 can be performed on its own. Although blocks 402-416 can be performed in order as described herein, blocks 402-416 can be performed in other orders, with some blocks being performed before, during and/or after other blocks in any permutation thereof Also, note that process 400 can be implemented with password entry, which can be based at least in part on alphanumeric input, symbolic input, biometric input, hardware input and/or others. However, process 400 can also be implemented without use of passwords.

In block 402, a plurality of variables are provided. Such provision can be manual and/or automatic, encrypted and/or unencrypted, wired and/or wireless, direct and/or indirect. Note that any number of variables can be used. For example, variable A, variable B, and variable C are provided where variable A is set to 17, variable B is set to 13, and variable C is set to 24. Note that the variables are in one numeral system, but in other embodiments, are in different numeral systems.

In block 404, a lookup table is provided. Such provision can be manual and/or automatic, encrypted and/or unencrypted, wired and/or wireless, direct and/or indirect. The table indexes a symbolic library, such as an alphanumeric library via a plurality of decimal values corresponding to the alphanumeric library. For example, a lookup table is provided below. Note that other types of lookup tables and different indexing libraries can be used as well, such as via other symbols, other numeral systems, and so forth.

Lookup Table 1 a 2 b 3 c 4 d 5 e 6 f 7 g 8 h 9 i 10 J 11 K 12 L 13 m 14 n 15 o 16 p 17 q 18 r 19 s 20 t 21 u 22 v 23 w 24 x 25 y 26 z 27 —

In block 406, a message is converted into a first numeral system via the lookup table. Such conversion is automatic and can be for any type of numeral system. The message can be manually and/or automatically generated, such as for telecommunications. The message is textual, but can be of any type. For example, if the message is hello_world, then, via the lookup table, the message is converted into a decimal system such that h=8, e=5, l=12, l=12, o=15, =27, w=23, o=15, r=18, l=12, d=4.

In block 408, the message, as manifested via the first numeral system, is converted into a second numeral system different from the first system. Such conversion is automatic, whether directly and/or indirectly, and can be for any type of numeral system, such as hexadecimal. Using the example above where h=8, e=5, l=12, l=12, o=15, =27, w=23, o=15, r=18, l=12, d=4, then such values are converted into a binary numeral system, which is different from the decimal system. Therefore, using 8 bit strings, the conversion results in 0000 1000 for h=8, 0000 0101 for e=5, 0000 1100 for l=12, 0000 1100 for l=12, 0000 1111 for o=15, 0001 1011 for =27, 0001 0111 for w=23, 0000 1111 for o=15, 0001 0010 for r=18, 0000 1100 for l=12, and 0000 0100 for d=4. Note that the strings can also be in other bit sizes, such as 4, 16, and others.

In block 410, the message, as manifested via the second numeral system, is combined into a character sequence. Such combination is automatic, whether directly and/or indirectly. Using the example above containing the strings 0000 1000, 0000 0101, 0000 1100, 0000 1100, 0000 1111, 0001 1011, 0001 0111, 0000 1111, 0001 0010, 0000 1100, 0000 0100, then the strings are combined into a character sequence 000010000000010100001100000011000000111100011 0110001011100001111000100100000110000000100.

In block 412, a plurality of subsequences are generated, via segmenting by alternation, at least two of the variables from block 402. Such generation is automatic, whether directly and/or indirectly. Using the examples above containing the sequence 000010000000010 1000011000000110000001111000110110001011100001111000100100000110000000100 and where variable A is set to 17 and variable B is set to 13, then the subsequences are generated via alternating the variables to segment the stream. Therefore, the sequence 00001000000001010 00011000000110000001111000110110001011100001111000100100000110000000100 is segmented via alternating variable A and variable B such that the subsequences are generated via alternation and correspondingly sized according to alternation based on variable A and variable B. Resultantly, the subsequences are 0000 1000 0000 01010 (17 bits according to variable A), 0001 1000 00011 (13 bits according to variable B), 0000 0011 1100 01101 (17 bits according to variable A), 1000 1011 10000 (13 bits according to variable B), 1111 0001 0010 00001 (17 bits according to variable A), and 1000 0000 100 (11 bits according to variable B).

In block 414, the subsequences are converted into other subsequences using at least one of the variables, as provided via the block 402, different from the variables already used, as described above. Due to a value of the at least one of the variables being different from the variables already used, such conversion results in the other subsequences being of different length from the subsequences generated via the block 412. Such conversion is automatic, whether directly and/or indirectly.

Using the example above where the subsequences 0000 1000 0000 01010, 0001 1000 00011, 0000 0011 1100 01101, 1000 1011 10000, 1111 0001 0010 00001, and 1000 0000 100 are based on variable A and variable B, then such subsequences are converted into the other subsequences using variable C, which is set to 24. The conversion is based on a difference between variable C and a length of each of the subsequences. For example, the conversion of a 17 bit subsequence, based on variable A, into a 24 bit subsequence, based on variable C, is performed via adding 7 bits to the 17 bit subsequence to total to the 24 bit subsequence. Likewise, the conversion of a 13 bit subsequence, based on variable B, into a 24 bit subsequence, based on variable C, is performed via adding 11 bits to the 13 bit subsequence to total to the 24 bit subsequence. Therefore, the other subsequences result in different bit lengths from the subsequences as generated via the block 412. Resultantly, as converted via adding bits corresponding to the difference between variable C and relevant string length of the old subsequences, such as 17 or 13, the other subsequences are 0000 0000 0001 0000 0000 1010, 0000 0000 0000 0011 0000 0011, 0000 0000 0000 1111 1000 1101, 0000 0000 0001 0001 0111 0000, 0000 0001 1110 0010 0100 0001, and 0000 0000 0000 0100 0000 0100. Note that in other embodiments, the at least one variable is not different from at least one of the variables already used.

In block 416, the other subsequences are transmitted. Such transmission can be manual and/or automatic, direct and/or indirect, wireless and/or wired, encrypted and/or unencrypted.

For decoding based on process 400, using the examples above, then start with a received stream 0000000000010000000010100000000000000011000000110000000000001111100011 01000000000001000101110000000000011110001001000001000000000000010000000100. Then, the received stream is converted into word length from based on variable C, which is 24. Such conversion results in 0000 0000 0001 0000 0000 1010, 0000 0000 0000 0011 0000 0011, 0000 0000 0000 1111 1000 1101, 0000 0000 0001 0001 0111 0000, 0000 0001 1110 0010 0100 0001, and 0000 0000 0000 0100 0000 0100. Then, using variables A and B drop the added bits from each word, which results in 0000 1000 0000 01010, 0001 1000 00011, 0000 0011 1100 01101, 1000 1011 10000, 1111 0001 0010 00001, 1000 0000 100. Then, remove any separation, which results in 0000100000000101000011000000110000001111000110110001011100001111 000100100000110000000100. Then, segment the stream into 8 bit words, which results in 0000 1000, 0000 0101, 0000 1100, 0000 1100, 0000 1111, 0001 1011, 0001 0111, 0000 1111, 0001 0010, 0000 1100, 0000 0100. Then, convert the words into decimal equivalent, which results in 8, 5, 12, 12, 15, 27, 23, 15, 18, 12, 4. Then, use the lookup table and replace with hello world.

Variable Word-Length Encoding

In addition to added security, variable word length encoding may be used for encoding. In some cases, the variable word length encoding may be used for more efficient or higher resolution encoding. As will be understood by one of ordinary skill, a binary word is a collection of bits that together represent, for example, a unit, a number, a letter, or a symbol. In some applications, shorter word lengths may lack sufficient resolution, while longer word lengths may require excessive processing power and storage capacity to accomplish a given task. In some cases, variable word length encoding may address these and other limitations.

FIG. 5 shows a flowchart of an example embodiment of variable word length encoding according to the present disclosure. A process 500 includes blocks 502-510. Process 500 is for encoding and decoding logic using variable lookup tables and/or word length. Process 500 can be implemented via any combination of hardware logic, such as in one and/or more circuits on any hardware level, and/or software logic, such as in one and/or more software applications, which can be implemented below, on and/or above operating system level. Process 500 can be implemented in request-response computing. Process 500 can be a part of a larger process, irrespective of any relation to computer security. For example, various functions can be taking place before, during and/or after performance of any one and/or more blocks of process 500. Alternatively, process 500 can be performed on its own. Although blocks 502-510 can be performed in order as described herein, in some cases, some of blocks 502-510 can be performed in other orders, with some blocks being performed before, during and/or after other blocks in any permutation thereof.

In block 502, a default word length is determined. Such determination can be manual (e.g., set by a user) and/or automatic (e.g., determined by a processor). In some cases, the default word length may be set for the program. For example, the default word length may be, without limitation, 8 bits, 16 bits, or 24 bits.

In block 504, binary words of the default word length may be output in a default word length mode. For example, in a case where a default word length is 8, characters in the American Standard Code for Information Interchange (ASCII) table may be output.

In block 506, a predetermined binary transition word of the default word length may be output to indicate transition into a variable word length mode. For example, in the case that ASCII characters are output during the default word length mode, decimal 141, which is not used in the ASCII table, may be output to indicate transition into the variable word length mode.

In block 508, a binary length word following the transition word signifying the word length of the following bit stream may be output. In some cases, the length word may specify the word length of the following bit stream explicitly, i.e., the length word being a number of the word length of the following bit stream, or representatively, e.g., referencing a table indicating word-lengths.

In block 510, a bit stream of words of the indicated word length is output with an additional flag bit at the beginning of each word. The flag bit may indicate whether a next word is a word in the stream or a change in word length. For example, when the flag bit is 0, the following word is a word in the stream, and, when the flag bit is 1, the following word may be another length word. If the length word is an exit word, for example, all zeroes, the mode may transition to the default word length mode. However, this is just an example. In some cases, the flag bit being 1 may signify that the next word is another length word. In other cases, the flag bit being 1 may signify transition to the default word length mode, and the current word or the next word may be of a default word length depending on the embodiment.

As a non-limiting example, consider a case where the default word length is 8 bits representing ASCII characters, the transition word is decimal 141, the length word is 16 bits long and explicitly indicates the word length of the following bit stream, and a flag bit of 1 indicates that the following word is another length word. In this example, 2 ASCII characters, 3 four-bit words, 2 five bit words, and 3 more ASCII characters are output. Exemplary outputs for the case are illustrated below in Table 1:

TABLE 1 Output Stream Corresponding 01001000 2 ASCII characters of default word length 01101001 1001101 Transition word, decimal 141 000000000100 Length word, decimal 4 0 1010 4 four-bit words with flag bits of 0 0 0111 0 1001 0 0010 1 0000000000000101 Length word, decimal 5, with flag bit of 1 0 10001 2 five-bit word with flag bit of 0 0 11100 1 0000000000000000 Length table word, exit word, decimal 0 indicating transition to default word length mode, with flag bit if 1 01000010 3 ASCII characters of default word length 01111001 01100101

FIG. 6 shows a flowchart of another example embodiment of variable word length encoding according to the present disclosure. A process 600 includes blocks 602-610. Process 600 is for encoding and decoding logic using variable lookup tables and/or word length. Process 600 can be implemented via any combination of hardware logic, such as in one and/or more circuits on any hardware level, and/or software logic, such as in one and/or more software applications, which can be implemented below, on and/or above operating system level. Process 600 can be implemented in request-response computing. Process 600 can be a part of a larger process, irrespective of any relation to computer security. For example, various functions can be taking place before, during and/or after performance of any one and/or more blocks of process 600. Alternatively, process 600 can be performed on its own. Although blocks 602-610 can be performed in order as described herein, in some cases, some of blocks 602-610 can be performed in other orders, with some blocks being performed before, during and/or after other blocks in any permutation thereof.

In block 602, a default word length is determined. Such determination can be manual (e.g., set by a user) and/or automatic (e.g., determined by a processor). In some cases, the default word length may be set for the program. For example, the default word length may be, without limitation, 8 bits, 16 bits, or 24 bits.

In block 604, binary words of the default word length may be output in a default word length mode. For example, in a case where a default word length is 8, characters in the American Standard Code for Information Interchange (ASCII) table may be output.

In block 606, a predetermined binary transition word of the default word length may be output to indicate transition into a variable word length mode. For example, in the case that ASCII characters are output during the default word length mode, decimal 143, which is not used in the ASCII table, may be output to indicate transition into the variable word length mode.

In block 608, a bit stream of words is output with a key at the beginning of each word indicating a length of the word. The key may be any number of bits, for example 3, and may map to specified word lengths. In some cases, the key may be immutable. In some cases, a header may indicate the key. For example, a header may indicate word-length values corresponding to a two bit key.

In block 610, an exit word may be output indicating transition back to the default word length mode. For example, in the case that ASCII characters are output during the default word length mode, when the key indicates an 8 bit word, decimal 143, which is not used in the ASCII table, may be output to indicate transition into the variable word length mode.

As a non-limiting example, consider a case where the default word length is 8 bits representing ASCII characters, the transition word is decimal 142, the exit word is decimal 143 in an eight bit word, and the key is three bits using the following key:

Key Word Length 000  8-bit word 001  16-bit word 010  24-bit word 011  32-bit word 100  48-bit word 101  64-bit word 110 128-bit word 111 256-bit word In this example, 2 ASCII characters, 1 64-bit word, 2 sixteen bit words, and 3 more ASCII characters are output. Exemplary outputs for the case are illustrated below in Table 2:

TABLE 2 Output Stream Corresponding 01001000 2 ASCII characters of default word length 01101001 1001110 Transition word, decimal 142 101 0010000000000000 Key followed by 64 bit word 0000011001000001 0100100101000000 0100011111000000 001 1010011110010010 Key followed by 16 bit word 001 1100100010101001 Key followed by 16 bit word 000 1001111 Key followed by exit word, decimal 143 in 8 bits 01010000 3 ASCII characters of default word length 01000010 01001101

In some cases, a key may be added at the beginning of each word indicating a length of the word, and a default word length may not be determined. In other words, every word has a key that indicates the length of the word. As in the embodiment discussed above with reference to FIG. 6, the key may be of any number of bits.

As a non-limiting example, consider a case where and the key is three bits using the following key:

Key Word Length 000  8-bit word 001  16-bit word 010  24-bit word 011  32-bit word 100  48-bit word 101  64-bit word 110 128-bit word 111 256-bit word In this example, 2 8 bit characters, 1 64 bit word, 2 sixteen bit words, and 3 more 8 bit characters are output. Exemplary outputs for the case are illustrated below in Table 3:

TABLE 3 Output Stream Corresponding 000 01001000 Key followed by 8 bit word 000 01101001 Key followed by 8 bit word 101 0010000000000000 Key followed by 64 bit word 0000011001000001 0100100101000000 0100011111000000 001 1010011110010010 Key followed by 16 bit word 001 1100100010101001 Key followed by 16 bit word 000 01010000 Key followed by 8 bit word 000 01000010 Key followed by 8 bit word 000 01001101 Key followed by 8 bit word As can be seen by comparing Table 3 with Table 2, in some embodiments, because there is no default word length mode, no transition word or exit word is used to transition to the variable word length mode.

In some cases, a binary length word may signify the word length of the following bit stream before each sequence of words, and an additional flag bit may be included at the beginning of each word to indicate whether a next word is a word in the stream or a change in word length. As in the embodiment discussed above with reference to FIG. 5, the length word may specify the word length of the following bit stream explicitly, i.e., the length word being a number of the word length of the following bit stream, or representatively, e.g., referencing a table indicating word-lengths.

As a non-limiting example, consider a case the length word is 16 bits long and explicitly indicates the word length of the following bit stream, and a flag bit of 1 indicates that the following word is another length word. In this example, 2 eight-bit words, 3 four-bit words, 2 five bit words, and 3 more eight-bit words are output. Exemplary outputs for the case are illustrated below in Table 4:

TABLE 4 Output Stream Corresponding 1 0000000000001000 Length word, decimal 8, with flag bit of 1 0 01001000 2 eight-bit words with flag bits of 0 0 01101001 1 000000000100 Length word, decimal 4, with flag bit of 1 0 1010 4 four-bit words with flag bits of 0 0 0111 0 1001 0 0010 1 0000000000000101 Length word, decimal 5, with flag bit of 1 0 10001 2 five-bit word with flag bit of 0 0 11100 1 0000000000001000 Length word, decimal 8, with flag bit of 1 0 01000010 3 eight-bit words with flag bits of 0 0 01111001 0 01100101 As can be seen by comparing Table 4 with Table 1, in some embodiments, because there is no default word length mode, no transition word is used to transition to the variable word length mode.

Based on the use of variable word length encoding, bit streams may be transmitted and processed quicker, file sizes may be smaller, and higher resolution may be provided when necessary. In some cases, a default word length may be set before hand. In some cases, a file may be scanned, and word lengths, such as default word lengths, may be set to improve compression. In some cases, a file may be scanned and a default word length and variable word lengths may be optimized. In some cases, a default word length may not be set, and the encoding may only be performed in a variable word length mode.

 4. The method of claim 2 further comprising: outputting, after a respective flag bit indicates that the corresponding second data word is a last second data word of the at least one second data word, an exit word indicative of transitioning to the default word length mode; parsing a third portion of the data into at least one third data word having the default first word length; and outputting, after the exit word, at least one third data word having the default first word length.
 5. The method of claim 4, wherein a word length of the exit word is the same as a word length of the first word length word.
 6. The method of claim 1 further comprising: outputting, immediately after each second data word of the at least one second data word, a respective flag bit indicative of whether the second data word is a last second data word of the at least one second data word.
 7. The method of claim 1 further comprising: outputting, immediately before each second data word of the at least one second data word, a respective flag bit indicative of whether the second data word is a last second data word of the at least one second data word.
 8. The method of claim 1, wherein the default first word length is 8 bits, the transition word is of the default first word length, and the transition word is not assigned to an ASCII character.
 9. The method of claim 1, wherein the first word length word has a value that is mapped to the second word length.
 10. A method comprising: outputting a plurality of word length words; parsing a first portion of data into a plurality of first data words, each of the plurality of first data words having a respective word length; and outputting, after each of the plurality of word length words, a corresponding first data word of the plurality of first data words, each of the plurality of word length words indicative of the respective word length of the corresponding data word.
